The mass of Neptune is about 1.03x10^23 metric tons. The mass of the sun is about 1.998x10^27 metris tons. About how many times the mass of Neptune is the mass of the sun? Round to the nearest thousandth, if needed use scientific notation. Use the multiplication symbol in the math palette as needed.
(1.998*10^27)/(1.03*10^23) = 1.9398*10^4 (round to nearest thousandth.)
When dividing, you subtract exponents.
Use asterisk (*) to indicate multiplication, because x is often used to indicate an unknown.
